Looks like a Losi XX buggy (not a JR, that was in the JRX series). There is a 2nd edition of sorts, called the XX-CR along with a few 'special' editions celebrating Kinwald (XX-KE). It appears you just need to pop the ball cups back on? They look a little knackered, you can still pick up the Losi ball caps on ebay and some local shops may still have them on the wall, or go for some RPM. JConcepts makes some nice ones, you can even use AE if you have to, just keep in mind the last 2 are a bit shorter, you may need to get longer linkages to use them in a pinch. You can always go all out and purchase all new ball ends, from the Losi 22 series & then upgrade all the ball cups to the most current Losi offerings as well. It was be pretty truck, but maybe more than you want to invest in your Vintage racer. Ditch the HydraDrive if you plan on racing it, use current slipper plates & pads/spur (again, 22 series is fine) to bring the spur area up to modern standards. Give the shocks a rebuild, toss in current electronics and go racing
